A few thoughts from Edward de Bono

"Logic is the tool that is used to dig holes deeper and bigger, to make them altogether bigger holes. But if the hole is in the wrong place, then no amount of improvement is going to put it in the right place."

"It is not possible to look in a different direction by looking harder in the same direction."

"Rejection is only exchanging positive discrimination for negative domination, and instead of weakening the dominant idea it may even strengthen it."

"The water in the well is not defined by the shape of the receptacles that are used for withdrawing it."
